Redundancy is used to comply with the strict requirements for
uninterrupted operation. Power systems consisting of several units must
be sized to ensure that in the that event one system is down, sufficient
capacity remains to power the load. In practical terms this means that
the individual systems never operate at full load.

Installed in parallel, the Silcon's intelligent control can also
improve overall efficiency because only the systems needed to supply the
load are "active." The other systems can be held in
"stand by" mode, ready to start up without interruption when
required.

Furthermore, to reduce stress and improve reliability, the load can
be switched between the parallel systems in preprogrammed sequences.
